The Powerful 3-Speed Hydraulic Diamond Core Drill

This 3 - speed hydraulic diamond core drill is perfect for heavy - duty wet drilling in concrete, reinforced concrete, and asphalt. With a mechanical slip clutch design, it offers three load speeds: 380 / 900 / 1800 RPM. It has a 3.6 HP (2.8 kW) motor weighing 16 lbs. You can use it hand - held for up to 3 - 1/4' diameter holes or mount it in a drill stand for up to 6' diameter holes. The industry's first 3 - speed hand - held design features a sealed 3 - speed gearbox with permanent oil bath lubrication. The hydraulic motor runs at 2000 PSI oil pressure with a 6 GPM required flow. Standard connecting threads include 5/8' x 11 UNC, 1 - 1/4' x 7 UNC, and G 1/2'. It comes with a 1/2' hose diameter and 3/8' FF (HTMA) couplings. Ideal for professional drilling contractors and underwater work, optional accessories are also available.

Using this drill is straightforward. First, decide whether you want to use it hand - held or mount it on a drill stand. For hand - held use, it's suitable for holes up to 3 - 1/4' diameter. When using the drill stand, you can drill holes up to 6' diameter. Make sure the hydraulic motor is connected with the correct oil flow and pressure. The required oil flow is 6 GPM at 2000 PSI. When connecting the hoses, use the provided 1/2' ID hose with 3/8' FF (HTMA) couplings. As for the water connection, use the included 3/4' Gardena system. When drilling, start at a lower speed and gradually increase if needed. Remember, this drill is designed for concrete, reinforced concrete, and masonry materials. For maintenance, keep the 3 - speed gearbox lubricated as it has a permanent oil bath. Check the mechanical slip clutch regularly for proper functioning. And if you're not using the drill for a long time, store it in a dry place. Optional accessories like the anchor stand can enhance your drilling experience, so feel free to use them as per your needs.
